METHOD FOR OPERATING A STEERING SYSTEM FOR A MOTOR VEHICLE AS WELL AS A CORRESPONDING STEERING SYSTEM
First Claim
1. A method for operating a steering system for a motor vehicle, wherein the steering system has at least one steering lever and at least one electric motor for shifting the steering lever so as to cause a steering movement in the presence of a steering input, and wherein the electric motor is electrically connected to a current source via cabling, wherein the electric motor is actuated and an electric current flowing between the current source and the electric motor is measured in order to check an electrical connection between the current source and the electric motor under the condition that there is no steering input present, whereinthe electric motor is actuated to generate or receive reactive current such that the steering movement stops, and/orthe electric motor is actuated for shifting the steering lever, wherein the actuation takes place when the vehicle is stopped and/or with a steering lever set by means of a locking mechanism.

Abstract
A method for operating a steering system for a motor vehicle, wherein the steering system has at least one steering lever and at least one electric motor for shifting the steering lever so as to cause a steering movement in the presence of a steering input, and wherein the electric motor is electrically connected to a current source via cabling. In doing so, it is provided that the electric motor is actuated and an electric current flowing between the current source and the electric motor is measured in order to check an electrical connection between the current source and the electric motor under the condition that there is no steering input present.

10. A steering system for a motor vehicle, comprising:
-
at least one steering lever and at least one electric motor for shifting the steering lever so as to cause a steering movement in the presence of a steering input, and wherein the electric motor is electrically connected to a current source via cabling, wherein the steering system is designed to check an electrical connection between the current source and the electric motor under the condition that there is no steering input present, to actuate the electric motor, and to measure a current flowing between the current source and the electric motor, wherein the electric motor is actuated to generate or receive reactive current such that the steering movement stops, and/or the electric motor is actuated for shifting the steering lever, wherein the actuation takes place when the vehicle is stopped and/or with a steering lever set by means of a locking mechanism.
